PZ: I don't need to preach atheism -- all I need to do is point out the palpable structure of reality in the growing detail science provides for us, and those who are awake and aware will notice the disparity between the world around them and the clumsy, sterile, ludicrous fantasies of religion, and they'll eventually abandon faith. Or, at least, they'll throw away dogma and retire faith to a smaller, private part of their lives.
The Universe: it's the Anti-Religion.
